Often natural disasters leave little intact DNA with which to identify the victim's remains using traditional DNA fingerprinting techniques.The discovery of ______ made genetic analysis possible with minute amounts of genetic material.

Question

Quizplus · Accepted Answer

SNPs (Single nucleotide polymorphisms) are variations in a single nucleotide that occur in the DNA sequences of individuals. SNPs can be used to distinguish individuals and have become a valuable tool in forensic analysis. SNP analysis can be performed on small amounts of DNA, which makes it useful for identifying victims in natural disasters where intact DNA is scarce. MiRNAs (A) and microarrays (D) can also be used for genetic analysis, but they are not specifically designed for identifying individuals and are not as widely used in forensic analysis. Frameshift mutations (B) are not suitable for identifying individuals as they are random changes in DNA sequence that can occur spontaneously or in response to different environmental factors.
